Where is the evidence for their being 100m high at the OM?
Where is the evidence for 6.8m/sec?
Have a look at my graphic or check out the CVR

10:39:49,9 ATC: Approaching outer marker, on course and path, distance 6.
10:39:50,2 [Beep sound, F 845Hz. Outer marker]
10:39:52,2 A: Outer
10:39:57,1 A: 400 meters.

That is, 7 seconds after after crossing the outer marker, they were still at 400 meters, while the FAF was at 300m. Then again, maybe the approach plate (from 2005) we all are referring to is not the one valid at that day???

Another thing:
I am pretty convinced now, that they actually initiated the GA after it was called by the 2nd Pilot at 80m height.
This is from the TU-154M FM and shows that at a sinkspeed of around 7 m/s the loss of height due to inertia when leveling out is around 40m.



That matches my drawing quite nicely, cause after the GA call, the A/C had lost the corresponding 40m down to the lowest level of its flight curve before gaining height again.
